WIRE-DRAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 672,568, dated April 23,1901.

Application filed July 18, 1900l To all whom t mayconcerm Be tknown that I, JOHN H. ODONNELL, of Waterbury, New Haven county, State of Connecticut, have invented a new and useful Improvement in Wire-Drawing Machines, of which the following is a specification.

A machine embodying the invention will be described and afterward its novel features will Vbe pointed out in the claims.

In' the accompanying drawings, Figure l is a top View of a machine embodying the improvement. Fig. 2 is a side elevation. Fig. 3 is a view of the front end of the machine. Fig. 4 is a transverse section at the plane of the dotted line 4; 4, Fig. l. Fig. 5 is a transverse section at the plane of the dotted line 5 5,`Fig. l. Fig. `tl is a longitudinal section at the plane of the dotted line 6 6, Fig.` 1.

Similar letters of reference refer to corresponding parts in all the figures of the drawings.

A designates wire to be drawn. It passes `first through a die-holder B', then around a Y bevel gear-wheels CZ d2 d3, which mesh into bevel gear-Wheels f, affixed to a shaft F, mounted in bearings f', comprised in the frame E and constituting adriving-shaft. It will benoticed that the bevel gear-Wheel d is larger than the bevel gear-wheel d2 and that the bevel gear-wheel d2 is larger than the bevel` gear-wheel d2, so that theroll or head C2 will be rotated more rapidly than the roll or head C' and the roll or head C3 will berotated more rapidly than the roll or head C2.' Leaving the roll or head C2, the wire A extends backward to an idler-pulley G', mounted loosely upon the shaft D', and thence it passes through a die-holder B4. After emerging from the die-holder B4 the Wire passes around a roll or head C4, which is rigidly afflxed to the shaft D2, but is so much larger in diameter than the roll or head C3 Serial No. 24,027. (No model.)

that it moves at a greater surface speed, although the shaft D2 carrying it rotates less rapidly than the shaft D2, carrying the roll or head C2. After passing around the roll or head C1 the Wire passes through a die-holder .a faster surface speed than the surface speed of the roll or head C5, because of its larger diameter, notwithstanding that the shaft D3, carrying the roll or head C5, is rotated more rapidly than the shaft D2. The wire after passing around the roll or head C6 passes through a dieholder B7. Subsequently it passes around a roll or head C7, affixed to the shaft D2. Next it passes through a die-holder B8, and from there it passes to a head or reel C8.

The head or reel C8 is affixed to a shaft G,

journaled in a bearing provided in a bracket g', which is mounted upon a block G10, fitted to slideways provided at the forward end of the frame E. Bolts g2, fitted to the slide-block G1o and passing through slots formed longitudinally in the slideways supporting said slide-block, serve to clamp the slide-block to the slideways in dierent positions. Provision is thus afforded for using a head or reel C8 of any desired size and shifting it so that its circumference will be in alinement with the Wire passing from the last die-holder BB.

Rotary motion is imparted'to the head or reel C8 by means of a bevel gear-wheel g3, affixed to the shaft G and engaging with a bevel gear-wheel g4, affixed to the horizontal shaft G12. Loosely mounted on the shaft G12 is a bevel gear-wheel g5, and this bevel gear-wheel is connected to one part g6 of a clutch. The other part g7 of the clutch is connected with the shaft G12 by a spline, so as to rotate therewith, but is free to slide relatively to the part g1i of the clutch. It has a circumferentiallygrooved hub, with which engage pins extending from a lever G3. By moving this lever in one direction the two parts of the clutch will be engaged and motion will be transmitted IOO 1. of a shank-like part b and a head b2.

- with a socket b2 for a rotary die.

from thegpart 'Q6 of the clutch tol the part g" of the clutch and thence to the shaft G12. The shaft G12 is supported near one end in a bearing connected with the slide-block G10 and, at the other end With a bearing with which the iframe E isprovided. Thebevel gear-Wheel g5 engages With a bevel gear-wheel g8 on the shaft Rand consequently the bevel gear-Wheel g5 rotates continuously while the shaft F is in operation. When one head or reel is substituted for another, change of speed of the shaft G Will have to be made. This may be done by substituting adifferent pair of gear-Wheels for the pair of gear-Wheels g2 g4 or forthe pair of gear-Wheels Q6 gs.

The shaft F derives motion from a belt applied to a pulley H,`Which, as hereshown, is a clutch-pulley of suitable'form, Which may be engaged and disengaged from the shaft F by means of a' lever h', rod h2, rocker-arm h6, and a treadle h4. Preferably the'treadle h4 will extend throughout the length of the machine, so vthat a Workman may operateit Vfromany point Where he may be Working so asto start or stop the machine.

The die-holders B B2 B3 B4 B6 B6 B7 B6 are supported by brackets B. They are all secured to the frame'E. The first bracket B is l provided only With the single non-rotary die holder B. Thesecondbracket Bis provided with rotary die-holders B2 B4 B6. -Thethir'd bracket B isprovided with rotary die-holders B3 B5 B7, and the last bracket B is provided with the rotary die-holder B6. The construction of the die-holders is illustra-tedupon an enlarged scale in Fig. 6.

It will be seen that each die-holder consists The shank-like part b ts in a bearing 'b in one of the brackets B. The head is provided There isa longitudinal slot from the interior to^the eX- terior ofthe shank b of each` of these die- 'holders, and a 4corresponding .slet through the head b and also through the bracket B, so that the rotary dies after having been ystrung upon the Wire may be introduced by 'adj usting the rotary die-holders so that their slots will be in line with the slots of the* brackets B and then entering the'wire by a movement transverse to its length,`the dies being afterward moved lengthwise into their sockets h6.

To facilitate the rotation of the rotary dieholders, they are provided vwith ball-bearings b4, intermediate of their heads `b2 and the brackets B.

A gear-Wheel b5 is arranged vupon the head b2 of each rotary die-holder to provide for rotating the same and with it the rotary die which it carries. The gearwheels 66 on the rotary die-holders'B2 B4 B6 intermesh. With the gear-'Wheel h6 of the rotary die-holderB2 intermeshes a gear-Wheel h6, arranged upon 'a stud extending from the'bracket'B, sup-V porting the said rotary die-holders B2 B4 B6.

The gear-Wheel h6 meshes with a gear-Wheel 197 upon a shaft I, supported by the brackets B, and by a bracket bg, affixed to the frame E. The gear-Wheel h6 of the rotary die-holder B6 meshes With a gear-Wheel b9, aixed to a p `stud projecting from the bracket B,support 1914, mounted upon studs projecting from the Vbracket B, supporting the rotary die-holder B8, and the gear-wheel 514 meshes with a gearwheel Z916, axed to "the shaft I. Owing to `the'nurnbe'r of gear-'wheels in the train transmitting motion from the shaft Itothe -rotary die-holders supported'by'the severalbrackets B'the rotary die-holders B2 B4B6 'will rotate in one direction,- while the rotary die-holders B3 B5 Blwill rotate 'in the Yreverse :direction andthe'rotary die-holder Bg'will rotatein the same direction as the rotary die-holders B2 B4 B6. i

The shaft I 'has `mounted upon it a gear- Wheel t", Which engages with agear-'wheel 2, afiixedtoa shaft supported l*in'aloracket i6, fastened to the Aframe E, and "provided'with agear-Whe'el 4,fthat meshes'with a gear-Wheel Q16, affixed to the shaft D. Rotary-motionis thus 'transmitted 'from the 'shaft D to "the bevelgear-wheel iupon'the shaft I. 'This IOO bevel gear-Wheel t" is furnishedwithone lpart of a clutch. The otherpart i6 of theclutch is secured to the shaft I, so as to be tree to slide'al'ongthe same,.but so as not'tobe capa- 'ble of independentrotary movement. It may be secured'to the shaftby'a spline. A lever or otherdevice engaging the par-f, 6 maybe i employed for shifting `the part l6"lengthwise 'of' the shaft'to Aengage and dis'engageiitand 'th e other part-of the `clutch which isiformed with the bevel gear-,Wheelol Thjertwoiparts of the clutch areto be engaged duringthe runningo'f the machine; ibut-While thefdes are'in place in the die-holdersthe parts `of the clutchwll be disengaged. Thus the shaft I willbe left free 'to be kturned "byfhan'dlfor the purpose of adjusting `the rotary dieholders so that their'slots will ybe'upp'ermost and in alinem'ent'with thecorresponding slots vof the brackets B.
